Magazine well

ABSTRACT

A magazine well formed in a lower receiver of a firearm is provided. The firearm may be a rifle and particularly a tactical rifle such as, but not limited to an AR-15. The magazine well accepts more than one type of magazine. Each type of magazine operates to hold a size of ammunition that differs from the other magazines. This allows users to shoot varying sized or caliber ammunition from the same firearm by simply changing the magazine that is loaded with varying size or caliber ammunition.

CROSS REFERENCE TO RELATED APPLICATION[S]

This application claims priority to U.S. Provisional patent application entitled “MAGAZINE WELL,” Ser. No. 62/350,101, filed Jun. 14, 2016, the disclosure of which is hereby incorporated entirely herein by reference.

BACKGROUND OF THE INVENTION Technical Field

This invention relates generally to a magazine well of a firearm and more particularly to a magazine well a firearm that accepts more than one type of magazine.

State of the Art

Firearms, and in particular rifles may include a magazine well and accepts a magazine that may be loaded with ammunition. The magazine well is a component of the firearm that receives the magazine and operates to provide ammunition to a position for discharge. The drawback with conventional magazine wells is that they are generally configured to receive a single type of magazine and thereby restricts the size of ammunition that may be discharged from the firearm.

There is a need in the field of magazine wells for an improved magazine well capable of accepting more than one type of magazine.

DISCLOSURE OF THE INVENTION

The present invention relates to a magazine well formed in a lower receiver of a firearm, such as a rifle and particularly a tactical rifle such as, but not limited to an AR-15, wherein the magazine well accepts more than one type of magazine. Each type of magazine operates to hold a size of ammunition that differs from the other magazines.

An embodiment includes a magazine well formed in a lower receiver, the magazine well comprising: a substantially flat rear surface; and an inner volume extending through the magazine well, wherein the inner volume receives one of a first magazine or a second magazine wherein the first magazine is loaded with a first size ammunition and the second magazine is loaded with a second size ammunition, the second size ammunition is larger than the first size ammunition.

Another embodiment includes a double stack magazine comprising: comprising a substantially flat rear surface; and an outer dimension to couple within a magazine well configured to receive the double stack magazine or a conventional magazine, wherein the magazine is loaded with ammunition that is larger than the ammunition that is loaded within the conventional magazine.

Yet, another embodiment includes a lower receiver and magazine system comprising: magazine well formed in the lower receiver, the magazine well comprising: a substantially flat rear surface; and an inner volume extending through the magazine well; and a double stack magazine loaded with ammunition that is larger than ammunition that is loaded within a conventional magazine, the double stack magazine comprising: a substantially flat rear surface; and an outer dimension to couple within the inner volume of the magazine well, wherein the substantially flat rear surface of the magazine engages the substantially flat rear surface of the magazine well.

The foregoing and other features and advantages of the present invention will be apparent from the following more detailed description of the particular embodiments of the invention, as illustrated in the accompanying drawings.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

As discussed above, embodiments of the present invention relate to a magazine well formed in a lower receiver of a firearm, such as a rifle and particularly a tactical rifle such as, but not limited to an AR-15, wherein the magazine well accepts more than one type of magazine. Each type of magazine operates to hold a size or caliber of ammunition that differs from the other magazines.

Referring to the drawings, FIGS. 1-3 and 11-18 depict an embodiment of a lower receiver 10 having a magazine well 12 that operates to accept more than one type of magazine. Particularly, magazine well 12 includes a rear surface 14 that is substantially flat, thereby creating a larger interior volume.

Comparing the lower receiver 10 with magazine well 12 to prior art lower receiver 30 with prior art magazine well 32 (shown in FIGS. 4-6), the differences can easily be determined. Prior art magazine well 32 includes a channel 34 extending along the length of the rear surface of the prior art magazine well 32. The prior art magazine well 32 is can receive a conventional magazine 20 shown in FIGS. 7 and 8. Conventional magazine 20 includes a protrusion 22 extending along a length of the magazine that corresponds to the channel 34 of the prior art magazine well 32. The prior art magazine well 32, however, does not have the proper size or configuration to receive new magazine 40 having a flat rear surface 42, as depicted in FIGS. 9 and 10.

The magazine well 12 of the current invention, however, includes a substantially flat rear surface 14 that is the same distance from the front surface of the magazine well 12 to the rear surface of the magazine well 12 as the distance from the front surface of the prior art magazine well 32 to the rear surface of the channel 34. This allows the new inventive magazine well 12 the ability to receive conventional magazine 20 and new magazine 40.

Conventional magazine 20 is a double stack magazine and allows a predetermined size or caliber of ammunition to be loaded in the conventional magazine 20 for discharge through the firearm. New magazine 40 is also a double stack magazine that is configured to allow a longer predetermined size or caliber of ammunition to be loaded in the new magazine 40. This is possible through the expansion of the inner volume of the new magazine 40 by forming a flat rear surface to provide the space necessary to load longer ammunition. In at least this way new magazine 40 is loaded with ammunition of a different size or caliber than the ammunition that may be loaded within conventional magazine 20.

The embodiments and examples set forth herein were presented in order to best explain the present invention and its practical application and to thereby enable those of ordinary skill in the art to make and use the invention. However, those of ordinary skill in the art will recognize that the foregoing description and examples have been presented for the purposes of illustration and example only. The description as set forth is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the teachings above without departing from the spirit and scope of the forthcoming claims.
